@dc42 yes I have “G4 S1;” in the line above the first reference to an external board. In this case it’s board 40, declaring its driving capability and pulse profile for later use in config.g.
I’m just perplexed as to why the issue of functionality the out0,1 pins aren’t consistent across both x1d boards while at the same time there is some functionality in each. (40 is driving y axis, 41 will eventually drive x axis but currently just used for temp0 and triggering SSR’s.
Thank you for the tip on calibration of temp0, I’ll proceed to tune this piece.
